Scarfing jig

[Scott Dunsworth]

I made this scarfing jig to speed up the hundreds of scarfs we will be making on our new project. I made it similar to one I seen on the Sailfar website. It makes 8 to 1 scarfs nearly perfect and very quickly. I scarfed these four boards for my keel batten in about ten minutes. They are very accurate. You use a straight trim bit set to the thickness of the stock.

Looks good, and the time savings you get using it makes it worth its weight in gold.

I hope to be able to scarf about 20 strip at a time with this contraption, we'll just have to wait and see. I am going to order some 5 min epoxy from Raka tommorrow to glue the strips up. Don't know how fast it will cure in the cold.

For wide boards Scott the router jig is superior to anything I have tried. I have used a similar jig (similar design but made out of polycarbonate) for components of box spars and repairs to box spars. As well as new construction it can scarf a damaged piece of a mast in place and it's mated replacement piece. For narrow pieces like gunwales, toe boards and kayak stringers I like the table saw sled.

Last night I did 136 scarfs on the strips. I can get 20 strips in the jig at a time. It takes a little time to line up and secure them. But I can make 40 really good 8 to 1 scarfs an hour. Most of my strip stock is 10 feet long so I probably only got about 5 or 6 hundred more to make.

It sounds like your jig is a good way to make the many duplicate scarfs. Keep in mind that some of the most dangerous operations with power tools are the repititious ones. It is easy to become complacent.

Your right, I like to have a rum and coke when it gets to repetitive. That way along with some blood in the boat you can also have some rum stains. Which is the single most important thing that must be done for a truly seaworthy boat.
